Describe the Bug

The table when exported using the ExportOption interface in PDF format, the exported file is not supported in chrome as well as Adobe pdf viewer.

Steps to Reproduce

Use this code on the export button click
exportTable() {
this.angularGrid.exportService.exportToFile({
filename: 'myExport',
format: FileType.pdf
})
}

Expected Behavior

We should be able open the downloaded file in any PDF viewer.

Current Behavior

When we try to open the downloaded file the following error messages arise.

1. Edge browser - "This PDF is corrupted"
   

2. Chrome - "Failed to load PDF document."
   

3. Adobe Acrobat Reader DC - "Adobe Acrobat Reader could not open the file"
   

Possible Solution

Code Sample

You can check this by changing the exportToFile method in the Example 12: Localization (i18n) class in the examples.
exportToFile(type = 'csv') {
this.angularGrid.exportService.exportToFile({
filename: 'myExport',
format: FileType.pdf
});
}

[ghiscoding]

You cannot use anything else but txt in the Export to File Service, I should (will) remove pdf from the list, it's not a valid option since there are no PDF Exporter Service.

So the best approach is to create a PDF Export Service, but I personally will not invest time in creating this. I never use grid PDF export, however I would certainly be happy to receive and accept Pull Request for this feature.

This is an Open Source project, if you want a new feature then please help and contribute.
